- Abstract
In order to ascertain the characteristics of stable isotopes in different water bodies and the relationship among water bodies in Jinqu Basin, precipitation samples were collected and representative surface water and groundwater samples were taken into account in the region. By analyzing the features of spatial distribution of the stable isotopes deuterium(2H) and oxygen-18(18O), the local precipitation equation was established and the water cycle model was analyzed based on the stable isotope characteristics of surface water and groundwater in Jinqu Basin. The sustainable utilization of groundwater by enviromental isotope (3H) and carbon-14 (14C) was evaluated. The results show that the slope and intercept of the local precipitation line equation in Jinqu Basin are greater than the global precipitation line equation. Surface water, quaternary loose pore water and red-bed pore fissure water are mainly supplied by precipitation. The cross flow of pore water in the quaternary loose layer supplies the red-bed pore fissure water. The characteristics of environmental isotope enrichment indicate that the groundwater discharges from the north and south of the basin to the center of the basin. The sustainable utilization of quaternary loose pore water is stronger than that of red-bed pore fissure water.
